You can put this solution on YOUR website! if 20 pounds of sea water contains 1.6 pounds of salt, how many pounds of pure water must be added to produce a mixture containing 5% salt?
:
The amt of salt remains the same
let x = amt of water added
1.6 = .05(x+20)
1.6 = .05x + 1
1.6 - 1 = .05x
x = .6/.05
x = 12 lb of water added
